any information would be nice.

so I had sex after my period, with a condom, and during it I felt like I had air bubbles in my hips and bladder so I told him to stop because it was painful. ever since then I get weird air bubble feelings below my stomach and I randomly get itchy or random pokes of pain on my vagina. it feels like cramps up there. i also have been constipated. i thought it could be pregnancy at first but now I think it's just built up air in there.
